BEAUTIFUL FACES ENHANCE VERBAL WORKING MEMORY PERFORMANCE: AN NIRS STUDY
摘要： In addition to material rewards (such as money, food, and liquid), various social signals, including facial attractiveness, are perceived as incentives. Although material and monetary rewards are known to enhance various aspects of cognitive performance, it is not clear whether and how social signals affect cognition. The present study focused on facial attractiveness and investigated its effects on working memory. In addition, we used near-infrared spectroscopy (NIRS) to characterize the activation in the dorsolateral prefrontal cortex (DLPFC), an area known to be involved in the processing of reward-related cues in working memory. Our results show that compared to the non-reward condition, the cue for attractive faces enhanced working memory performance, but DLPFC activation did not differ between these two conditions. These results provide new evidence that facial attractiveness enhances verbal working memory performance and function via neural mechanisms different from those characterized for other types of rewarding cues.

Feasibility of NIRS-based neurofeedback training in social anxiety disorder: behavioral and neural correlates
摘要： Attention biases towards threat signals have been linked to the etiology and symptomatology of social anxiety disorder (SAD). Dysfunction of the dorsolateral prefrontal cortex (dlPFC) may contribute to attention biases in anxious individuals. The aim of this study was to investigate the feasibility of near-infrared spectroscopy (NIRS) neurofeedback (NF) training—targeting the dlPFC—and its effects on threat-related attention biases of individuals with SAD. 12 individuals with SAD participated in the NIRS-NF training lasting 6–8 weeks and including a total of 15 sessions. NF performance increased significantly, while the attention bias towards threat-related stimuli and SAD symptom severity decreased after the training. The individual increase in neurofeedback performance as well as the individual decrease in SAD symptom severity was correlated with decreased responses to social threat signals in the cerebral attention system. Thus, this pilot study does not only demonstrate that NIRS-based NF is feasible in SAD patients, but also may be a promising method to investigate the causal role of the dlPFC in attention biases in SAD. Its effectiveness as a treatment tool might be examined in future studies.
